GRAIN-SHOCKER.

Specification of Letters Patent.

Patented July 23, 1918.

Application filed April 8, 1918. Serial No. 227,360.

To all whom t may concern:

Be it known that I, FRANK D. MARSHALL, a citizen 0f the United States, residing at Central City, in the county of Linn and State of Iowa, have invented certain new and useful Improvements in Grain-Shockers; and I do hereby declare the following to beV a full, clear, and exact description of the. invention, such as will enable others skilled in the art to which it appertains to make and use the. same.

This invention relates to harvesting machines, the object of the invention being to provide such machines with mechanism adapted to catch the bundles as delivered from the binder, until enough for a shock has collected, and then deposit them on the ground, right end up, and in a neat and compat shock.

The invention also includes means for singling` out a supplemental, cap-sheaf and dropping the same, when such cap-sheaf is desired.

Provision isl also made for binding the shock with twine, when desired, to prevent any displacement of the sheaves in the act of` dumping them on the ground. 4

The invention is fully disclosed in the description and claims following, reference being had to the accompanying drawings in Whichz Figure. 1 is a rear view of a device embodying my invention,` a few of the parts being in section. Fig. 2 is a fragmentary and sectional view in perspective, showing details of the feed mechanism to be more fully hereinafter described. Fig. 3 is a plan view, illustrating the operation of the invention. Fig. 4 is a View of the device in the act of dumping a shock, as seen from the line A4.- 4, looking toward the right.

In the dravving:,r,` the numeral 1 denotes a part of the main frame of a harvester of a familiar type, the adjacent dotted outline 2 indicating a part of the frame nearer the observer than the parts shown in full outline, and carrying gearing 3 which transmits m0- tiOn toa shaft 4. This might be a special Vshaft for the purposes of this invention, but

as shown it is one of the driving shafts connecting with the grain elevating apron, and has a continnons motion as the harvester is in operation, :Above this is shown the regn-l lar needle 5 mounted on its rock-shaft 6 under the binding table 7. Over the binding table is mounted the knetter, 8, the main driving shaft 9 of which carries the ejector or kicker arms 10. Certain modifications .in the construction of some of these parts will be described hereafter, but otherwise ihey may be of the common and well known l'o the sill 1 of the main frame is secured a laterally extending frame 11, suitably supported by truss-rods l2. This frame gives support for a standard 13 at its outer extremity, serving as one of the bearings for a shaft 14 which carries the shocker to be described presently. The other bearing 15 may be bolted directly to the sill 1. The side frame also serves to support intermediate gearing whereby motion at reduced speed is transmitted from the shaft 4 to the shaft 14, intermittently. This gearing is shown as a spur-gear 16 meshing with a smaller gear 17 on the shaft 4, and a bevel gear 18 revolving concurrently with the spur-gear 16, and in mesh with a larger bevel-gear 19 running loosely on the shaft 14. Adjacent to this bevel gear is a clutch 9.0, of the single-revolution type affixed to the shaft 14, as by a key 21. This clutch engages the bevel-gear b v a bolt 22 forced to engaging position by a spring 23. A shoulder 24 of the bolt engages a cam 25 forming part of a lever 26 pivoted in a fork 9.7 of the standard 13, and held to engaging position by a spring 28. When in this position the clutch is disengaged, and the bevel-gear may run freely on its shaft. The cam-lever extends by a tailpiece 29 into the path of a revolving cam` 30, which in its movement disengages the cam 25 and thus engages the clutch, which is automatically disengaged in a single revolution of the shaft 14, as will be evident.

To the enter end of the shaft 14 is attached. an arm 31, provided at its outer end with a bearing 32 for the pivot of the shockcarrier 33. This is in the nature of a sheetmetal basket, and preferably tluted at the sides to form seats for the sheaves 34, as deposited therein, six of these being here shown for a shock of convenient size. The basket as herein illustrated, may also be adapted to catch a single bundle crosswise, preferably with a pocket or trough 3,5 at the -'bottom to hold an extra sheaf, as shown in Fig. T3, this being the cap-sheaf when the shock isV inverted, as will be explained presently. Connecting with the basket pivot is a casting'36, Vto which the basket is securely attached. Near the bearing is a ratchet 37, with teeth corresponding in number to the flutes of the basket. An intermittent turning motion is imparted to the basket by a pawl 38 connecting with a cam-lever 39 actuated in one direction by acam-disk 40 provided with a number of inclined faces 4l to engage the inclined face 42 of the l cam-lever. VThis disk is mounted to revolve Yon the shaft 14,V and gets its step-by-step motion from the needlerock-shaft through a pawl 43 and suitable studsor the like`pro jections 44. The connection of this pawl with the rock-shaftmay be an offset arm 45 forming a part of the needle-arm. These pawls are retracted by means of springs 46 and 4 7, respectively. It Vwill be noted that the forward feed of the basket coincides with the retreat of the needle', Vthus immediately following the discharge of the bound bundle.

vThe cam 30, which hereV forms a part of the came-disk, is timed to coincide with the dischargeof the last bundle, and trip the clutch 20 into action. As soon as thisl takes place the basket and its load is slowly inverted, in the direction and in the manner indicated in Fig. 4, the movement of the harvester being shown by the straight arrow, and that of the basket bythe curved one. This latter movement should approximate thatof the harvester forward, so that the basket, after dumping the shock, rolls over the tops of the standing sheaves, without vention,v they are made ,somewhat wider than heretofore, and the forward one has its inner end spaced farther from the middle of the table edge, so as-to give space for abundle between it and the forward ejector, as shown inV F1'g-3. When bundles are deposited at the sides ofthe `basket this flap is locked in the-upstanding,position,and thus serves as ajfulcrum against which the bundle is turned from the dotted lineposition to that shown y by thedescendingbundle. The other flap,

which mayswing up andjdown at will, is preferably inclined at the inner end, and is so spaced as to give room for the descent of the bundle, whose head, in falling, pitches toward the near side'cfthebasket. 1f no capshea-f Vwere dropped in the basket the forward Hap might be' fixed in the upstanding position, but in dropping the cap sheaf this flap moves to the saine position as the rear flap, and 'the two thus serve as an 1nclined shelf to carry the bundle,vstill parallel Y with the harvester, to the middle of the basket, and drop it into its proper' trough. A simple device for shifting and locking the flap comprises a shortarm lattached to the flap; a stop-bar 52 adapted to slide up to release the flap, and downto lock it in position; a cam 53 cooperating with a roller l 54 to raise the bar, and a spring 55 toretract the same. The cam may be a part of the cam-diskalready described, and so timed as to release the flap for the depositing, ofthe cap-sheaf, and permit its return to the upf y standing position for all the others., rilh'e stop-bar is shown mounted in guides Y56'V forming parts Vof an extension'of the standard 13. Y

By changing the starting timeof revolu- Y y tion lof the basket in dumping, the act may be prolonged until an extrabundle is bound and discharged on the closed side or bottom of the basket, whence it rolls to the ground near the standing shock, and thus serves as a cap-Sheaf. The action of the flaps in this case is practically the same .as already described, but with suitable change in the timf ing of their action.

. 100 j Provision is .made for binding the whole Y.

shock with twine', toA prevent any possible i scattering of the bundles as dumped. `Suit ably mounted onthe casting 36`is a. knotter V57, the particular construction of. which forms no necessary'partiof'this invention', its

only practical difference from knotters in general' use being that it, instead o f-the needle, carries the twine, encircling thus l.the shock as the basket revolves. -A vcage'58 toV hold the ballV of twine is .attachedtothe gooseeneck 31, and the twine isledthroughy an eye 59 in an arm 60 projecting upwardly and laterally from said goosenecln-so a'sfto be outside the path ofthe knotter as the basket turns on its pivot. When the last bundle of the shockhas been ydropped into the basketjand the basketrbegins to turn to dump, the pinion 61 of ythe knetter engages a segment of gear 13a connecting with kthe standard 13, and the knot istied, the knotter y at the same time grasping theend ofthe twine leading tothe ball, in a manner that will be readily understood by :thosefamiliar with knetter construction.V VFThe shock as finally deposited on the ,ground thusfstiands in a compact mass, as shown inFig. 4.1l

f When conditions are such as not to require any binding of the whole shock, this feature may be dispensed withP i li It will be noted that the basket is suitably positioned to receive seven bundles, with but six feed* impulses. This .is due to the fact that at the sixth feed impulse the basket is carried to proper position to receive the cap-shcat, and at the succeeding impulse` the first otl a new series, the basket is in proper position to receive the tirst buttraised shea't', as. clearly shown in Fig. lVhen a capshe-af is not used, the sequence of such lecd impulses is not important.

When a knotter is used to bind the shock as a whole, the basket should be prevented from turning on its axis, so that the knetter may be properly actuated. This is etl'ectcd by means o't` a simple lock, shown in Figs. 1 and Q'. To the basket pivot is attached a notched' disk G2, which is engaged by a locklcver 63 pivotcdI at (il. The pawl 3S is shown passing through a slot G5 vin the lockdever, `which thus serves as a support for it, and has lugs or studs 3S to engage said locklever. Thepawl has a litt-lesurplus motion, as shown in Fig. l, and during this .interval o the loek-lever is released, before the forward feed of the basket begins. The locking action ot' the lock-lever of course coincides with the position of the basket at the end of the feed impulse.

It will be understood that the invention contemplates the collecting' of a shock either with or without an extra shea't` for a capshea, and in case such extra sheal' is collected with the rest of the shock it may be discharged on top, or alongside the others. It also contemplates the dropping of the cap-sheaf in any suitable manner on the bottom of the receptacle, flatwise, but not necessarily in a trough, since the end sought would be attained without any further depression of the capsheaf than would be scoured by spreading its ends, as by the weight ot the standing bundles as dropped upon it.

Having thus described my invention, I claim:
